i iMPRovEMENTIN-WHIFFLETREE Hooks.

. The Schedulegreferred to `in these Letters VPatent: and making part of the same.

To all lwhom. it'may concern Y VBe it known that I, JUDsoN KNIGHT, of Newark, in the county of Essex andfState f New J ersey, have invented a new and improved Whiftletree Hook; and

['lo hereby declare that the following is a full, clear, l 'and exact description the1'eof`,rcference being had'to the accompanyingdrawing.'

. l Drawing. j

. `Figure 1` isa perspective view. v L

Figure 2 is a longitudinal sectiolLgtaken on thc'rline a:a;oi`fig.'1. U r r Figure 3 is a eross-section, takenfou the line y y otfg. 2. f.

` The object of this invention is to -jprodnce a convenient and Vsafe `whiiietree l10ok`,and wliichwill he free from dirt auditheeffects of lcold; and to this end, l ,e i

My invention consists `in arranging and inclosing within a whiiletree case or ferrule, avlever and spring, all of which will behereinafter.specifically designated and set'forthin thefollowiug description.

-Ii1 the .accompanying drawing which forms'a part `Ais a metal .case'olz t'errule, inclosing n ly device,

which goes upon 4the ends ,of 4the whiflietree, up to `the metal plate D, which rests upon lugs d.

` This plate D is designed to iuclose the'pa-rts that operate the hook, so that they may be kept free from dirt, as also the action'ofxthe cold. f

, a is the clasp, wh'ichismade round without the case, and square within. To the square ypart of the clasp'is secured a lever, b, to open, the end oi which 'has fa slight projection tot within the end of the spiral spring C, which springpresses against thecase in a transverse direction.

. It isv onlynecessary to depress the .sp1-ing' very slightly in order to relieve the clasp'and remove thel cock-eye. j.

I am aware that springs have been used to operate clasps uponjwhiiiletree hooks,'but they have not been made practical, without incurring' too great au expense to make them available.

My invention has been reduced to practice and found to work well, and to giveentire satisfaction.

Having thus described my invention,

What'I claim, and desire t0 Secure by Letters-'Patent of the United States, isi The clasp a, when operated through the leverb, by means ofthe spiral spring C, said spring being ai'- ranged transversely within the case A, .the whole being inclosed or not, by plate D, \substantially.as

herein shown and described'. l

In testimony whereof I have signed my name hereto this 12th day of July, 1 870, in the presencezof two `tt-testing witnesses.
